Bug 13768: Correction of double quotes escaped into double quotes

Without the patch the translated pages for quotes.tt may have the problematic line broken.
So the js is broken too. The line with bad usage of double quotes escaped :
var sEmptyTable = _("No quotes available. Please use the \"Add quote\" button to add a quote.");
